6 WWE Storylines that were dropped without any explanation

#3 Hideo's attacker remains a mystery

Though there were hints, Hideo's attacker was never revealed before his release from WWE.

Hideo Itami joined the WWE's NXT division at arguably the best possible time. Alongside fellow indie darlings like Finn Balor, Sami Zayn, Kevin Owens, and Neville, the former KENTA was poised to be a big star in the yellow brand, until an injury derailed everything.

After suffering an injury, Itami had to be removed from a number one contender's triple threat match for Owen's NXT Title, making the match a singles affair between Finn Balor and Tyler Breeze. To write him out, Itami was found writing in pain outside the arena, as fans wondered who would have attacked the Japanese Superstar.

Unfortunately for Itami, his return took much longer than planned, and by the time he comeback happened in August the next year, the story had long been forgotten about. Though NXT did allude to who his attacker could have been during his absence, nothing was revealed. The closest fans got to an answer was that Owens walked past Itami moments after the attack, and though it makes sense for the Prizefighter to be the man responsible, Itami's attacker remains at large.
